MEMBUAT ALARM BANJIR SEDERHANA

Summary

In this video, viewers are guided by Bapak SQ through the process of creating a simple flood alarm. The aim is to detect floods early by using a battery, wire, Styrofoam, and aluminum foil. The alarm is assembled into a box with a small and large straw to sense water level rise. When the water touches the alarm, it will sound, indicating a flood. The tutorial is practical, emphasizing safety and seeking adult help for cutting parts. The final test shows the alarm successfully detecting water level increases, providing an early warning system.

Takeaways

• 😀 The video is a tutorial from School Center Sekolah Pembangunan Jaya, introducing a simple flood alarm device.
• 🛠️ The main purpose of the flood alarm is to detect rising water levels early to alert people of potential flooding.
• 🔋 The materials required for the project include a single-use battery, wires, scissors, a ruler, string, Styrofoam, plastic wrap, a small and large diameter straw, aluminum foil, and a marker.
• 📏 The dimensions for the box are specified as 3 cm by 4 cm, with specific points marked for drilling holes.
• ✂️ Safety is emphasized when using a cutter, suggesting that children ask for adult assistance to avoid injury.
• 🚿 The straws are cut to specific lengths, with the larger one being 10 cm and the smaller one being 16 cm, to fit into the holes in the box.
• 🔩 The assembly process involves attaching the straws to the box and ensuring they stand upright for proper functioning.
• 🏷️ Aluminum foil is used to cover the Styrofoam, and a marker is used to label the parts for clarity during assembly.
• 🔌 The electrical wiring involves connecting a black wire from the battery to the circuit and a red wire to the floor, with careful placement to ensure the alarm works correctly.
• 💧 The flood alarm is tested by simulating a flood condition, where the rising water level causes the alarm to sound, indicating a high water level.

Q & A

What is the main purpose of the simple flood alarm being made in the script?

The main purpose of the simple flood alarm is to detect floods early so that people can be alerted in advance when a flood occurs.

What are the materials required to make the flood alarm according to the script?

The materials required include a single-use battery, wire, scissors, a stick, string, a small and large diameter straw, plastic wrap, aluminum foil, and a marker.

What is the size of the box that needs to be made for the flood alarm?

The size of the box is 3 cm by 4 cm, meaning it is 30 cm long and 4 cm wide.

How far apart should the two points be that are marked on the box?

The distance between the first and second points marked on the box should be 4 centimeters.

Why is it recommended to ask for adult help when using a cutter in this project?

It is recommended to ask for adult help when using a cutter because it can be dangerous, and children should be supervised by an adult to ensure safety.

What is the length that the large diameter straw should be cut to?

The large diameter straw should be cut to a length of 10 centimeters.

How long should the small diameter straw be cut for the flood alarm?

The small diameter straw should be cut to a length of 16 centimeters.

What is the purpose of the aluminum foil and styrofoam in the flood alarm project?

The aluminum foil and styrofoam are used to create a barrier that will be affected by the rising water level, triggering the alarm when the water reaches a certain height.

How are the battery and wires attached to the styrofoam in the flood alarm?

The battery and wires are attached to the styrofoam using glue and are positioned such that the wires will make contact when the water level rises and the floating straw touches the upper styrofoam piece.

What happens when the water level rises and the small straw touches the upper styrofoam piece in the alarm?

When the water level rises and the small straw touches the upper styrofoam piece, the buzzer will automatically sound, indicating that the water level has risen and a flood is occurring.

What is the final step to test the flood alarm after assembling all the parts?

The final step to test the flood alarm is to simulate a flood by pouring water into the container and observing if the alarm sounds when the water level reaches the trigger point.
